Abstract

The utility model relates to a coal seam water injection hole packer with a novel pipe joint. The coal seam water injection hole packer with the novel pipe joint is characterized in that the pipe joint consists of a connecting pipe, an outer joint, a water injection hole and an inner joint A, wherein the connecting pipe is arranged between the outer joint and the inner joint A; the inner joint A is inserted into the inner hole of a rubber expansion pipe; the periphery of the end of the rubber expansion pipe is sheathed with a buckling locking jacket; the pipe joint which consists of the connecting pipe, the outer joint, the water injection hole and the inner joint A is tightly connected together with the rubber expansion pipe through extrusion between the inner joint A and the buckling locking jacket; the other end of the rubber expansion pipe is also provided with an inner joint B; one end of the inner joint B is inserted into the inner hole of the rubber expansion pipe; the other end of the inner joint B is connected with a connector; the outer end of the connector is provided with an overflow hole; a one-way ball valve and a spring are arranged in the connector; one end of the spring is contacted with the one-way ball valve; and the other end of the spring is contacted with the inner wall of the overflow hole. The coal seam water injection hole packer with the novel pipe joint has the advantages that the service life is long, and the phenomenon that the rubber expansion pipe is exploded due to unlimited swelling is greatly reduced.

Description

Coal seam flooding hole sealing device with new tube joint
Technical field
The utility model relates to a kind of coal seam flooding hole sealing device with new tube joint, is applied to the shutoff to holing on the colliery.
Background technology
Be used at present there is the drawback of easy explosion in the conventional hole packer of the use of mine shutoff in the shutoff process on the colliery, because hold when the bores are being drilled the unstability of drill bit due to operating personnel, can cause the opening part diameter of holing excessive and irregular, when the needs shutoff is holed, hole packer is positioned in boring, then water filling makes the rubber tube expansion that outlet is blocked, because the diameter of opening part is excessive, make the unconfined expansion of expansion tube, like this expansion tube of hole packer upper end and just easily explosion of the junction of withholding locking jacket.
Summary of the invention
technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of coal seam flooding hole sealing device with new tube joint is provided, and the utility model solves the technical scheme that its technical problem adopts and is: structure of the present utility model comprises tube connector, socket, water filling port, spigot A, the rubber swelling pipe, withhold locking jacket, non-return valve, connector, overfall gap, spring, spigot B is characterized in that union is by tube connector, socket, water filling port and spigot A form, and tube connector is arranged between socket and spigot A, and place, socket outer end is provided with water filling port, tube connector, socket, water filling port and spigot A are structure as a whole, and spigot A inserts the endoporus of rubber swelling pipe, and the periphery, termination of rubber swelling pipe is socketed with withholds locking jacket, by tube connector, socket, the union that water filling port and spigot A form links together with the rubber swelling pipe closely by spigot A and the extruding of withholding between locking jacket, the other end of rubber swelling pipe also is provided with spigot B, the end of spigot B inserts the endoporus of rubber swelling pipe, the other end of spigot B is connected with connector, the outer end of connector is provided with overfall gap, be provided with non-return valve and spring in connector, an end of spring contacts with non-return valve, and the other end of spring contacts with the inwall of overfall gap.
During use, the utility model hole packer is put into boring, then water filling makes Dilated rubber hose expand to block and bores mouth.The unstability that during due to boring, operating personnel hold drill bit, can cause the opening part diameter of holing excessive and irregular, an end that deviates from one way valve at hole packer increases by one section tube connector, when like this hole packer being put into boring, the tube connector that increases is placed in the opening part of boring, make like this bore diameter of Dilated rubber hose periphery almost consistent, thereby avoided the unrestricted expansion of Dilated rubber hose.
The beneficial effects of the utility model are that the utility model long service life greatly reduces the phenomenon because of the unrestricted expansion of Dilated rubber hose explosion.
Description of drawings
Fig. 1: the utility model embodiment cross-sectional view.
In figure: tube connector 1, socket 2, spigot 3, rubber swelling pipe 4, withhold locking jacket 5, non-return valve 6, connector 7.
The specific embodiment
Illustrate referring to the drawings the utility model is done following concrete detailed description.as shown in drawings, structure of the present utility model comprises tube connector 1, socket 2, water filling port 2.1, spigot A3, rubber swelling pipe 4, withhold locking jacket 5, non-return valve 6, connector 7, overfall gap 7.1, spring 8, spigot B9 is characterized in that union is by tube connector 1, socket 2, water filling port 2.1 and spigot A3 form, and tube connector 1 is arranged between socket 2 and spigot A3, and water filling port 2.1, tube connector 1 are located to be provided with in socket 2 outer ends, socket 2, water filling port 2.1 and spigot A3 are structure as a whole, and spigot A3 inserts the endoporus of rubber swelling pipe 4, and the periphery, termination of rubber swelling pipe 4 is socketed with withholds locking jacket 5, by tube connector 1, socket 2, the union that water filling port 2.1 and spigot A3 form links together with rubber swelling pipe 4 closely by spigot A3 and the extruding of withholding between locking jacket 5, the other end of rubber swelling pipe 4 also is provided with spigot B9, the end of spigot B9 inserts the endoporus of rubber swelling pipe 4, the other end of spigot B9 is connected with connector 7, the outer end of connector 7 is provided with overfall gap 7.1, be provided with non-return valve 6 and spring 8 in connector 7, one end of spring 8 contacts with non-return valve 6, and the other end of spring 8 contacts with the inwall of overfall gap 7.1.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
